Subject: Page count of PDF file from lua
Date: Sun, 19 Feb 2012 14:50:15 +0100 [thread overview]
Message-ID: <20120219145015.7fe6626d@homerow> (raw)
I can't figure out how to determine the number of pages of a PDF
file within lua. From the TeX side it works with
\getfiguredimensions
Can somebody give me a nudge in the right direction? Example:
\starttext
% Works
%\getfiguredimensions [somefile.pdf]
\startluacode
-- Does not work
context.getfiguredimensions({"somefile.pdf"})
local numpages = figures.get("used", "pages", 0)
context(numpages)
\stopluacode
\stoptext
Marco
